Ductless mini-split installation in New Germany costs $4,200–$12,500, written flat-rate, for upstairs rooms and enclosed porches. They suit upstairs rooms with no return, enclosed porches and homes still cooled by window units.
A typical New Germany house is a story-and-a-half from the depot era, with upstairs rooms finished after the heat was laid out. A single small supply and no return leaves those rooms cold in January and hot in July, because the knee-wall spaces beside them leak heat in winter and bake in summer. One ductless head in the upstairs room is often better than an attempt to run new ducts through a knee-wall attic, especially after the knee walls are sealed and insulated.
Many homes still use window units, and one head can replace two or three of them, with a single outdoor unit on the ground. Enclosed porches and additions finished after the original heating have no duct path at all, and a mini-split gives them heat and cooling without opening the walls. Farmhouses in Camden Township use the same idea for a shop or a bedroom wing.

Our $4,200–$12,500 installed price comes as a written flat-rate quote, with a 2-year labor warranty on top of the manufacturer's parts warranty. Rooms under steep roofs with knee walls take a smaller head after air sealing, and replacing several window units with multiple heads on one outdoor unit raises the total. Compare central AC vs ductless costs.
Xcel Energy supplies the electricity and has heat pump and AC rebates plus its own insulation and air sealing program; ask whether a given rebate requires a registered contractor. Township farms heating with propane generally won't get a gas utility's furnace rebate, but a heat pump can still qualify on the electric side. Rebate programs change every year, so check the utility's current terms before you buy.

Often, yes. A single head cools one room or an open area, so a home with two or three window units might need one or two heads, depending on the layout. The outdoor unit sits on the ground, and the window comes back out. We count the rooms and measure the load before we say how many.
It helps, but seal and insulate the knee walls first, because that is where much of the heat is leaking in summer and out in winter. Then a head sized to the room's smaller load keeps it comfortable. Without the sealing, the head runs more and costs more to operate.
